Trouble to recover damaged RAID 5

[lince2]

I used to have a desktop working with 4 Disks in Raid 5 system but after some power failure the system crashed and now I have the 4 disks but the RAID isn't working with all my files inside.
I'm not expert in linux therefore any help is welcome.

When I do the fdisk -l command this is what I get:

~# fdisk -l

I can't run my /dev/md2 drive as it get's a error and when I try and see the partitions I can only see the sdb2 and sdc2 to the other 2 parts (sdd2 and sde2) I can't do anything as example:

~# mdadm -E /dev/sdb2
/dev/sdb2:

sdc2 is the same... but:

~# mdadm -E /dev/sdd2
mdadm: cannot open /dev/sdd2: No such file or directory


It seem slike there are 2 disks out of the raid...
CAN ANYONE GIVE ME A HAND?
Many thanks in advance.

Perhaps someone lurking on the forums can help you recover your data. It's a day late, so to speak, but to run a system with RAID and no UPS with automatic shutdown software is just asking for total disaster. With normal discs, a power failure usually will leave you with the ability to run fsck on your file system(s) and recover most of your data, or all of it with a journaling file system such as ext3, jfs, etc. With a RAID, a power failure is likely to scramble the discs enough to be completely unrecoverable.

Thanks for your post. Although it isn't a tip to recover my data is always nice to have some concerned replys. My hope in this raid is 1 in a scale of 0-10 but I'm not givving up for the moment. I'm not a linux expert but maybe there is someone out there that just have the genius tip for me to do the right thing and then the miracle happens...
